To induce adipocyte differentiation by BMPs in the absence of induction cocktails, both WT brown preadipocytes and 3T3-L1 white preadipocytes were grown in regular growth medium supplemented with combination of rhBMPs (3.3 to 8.3 nM), insulin (20 nM) and T3 (1 nM) or vehicle as indicated in the text and figure legends for 7–13 days. To stimulate thermogenic program, differentiated cells were incubated with 500 µM dibutyrul cyclic AMP for 4 hrs. Cells were grown in growth medium without hormonal supplements for 18 hrs prior to cAMP stimulation.
C3H10T1/2 cells were grown in the presence and absence of 8.3 nM rhBMP-7 for 3 days to reach confluence (day 3). These cells were then induced to adipocyte differentiation using protocols described below for additional 7 days (day 10). Adipocyte differentiation was done by treating confluent cells for 48 hours in medium supplemented with 20 nM insulin and 1 nM triiodothyronine (T3), 0.5 mM isobutylmethylxanthine (IBMX), 5 µM dexamethasone, and 0.125 mM indomethacin. Cells were placed back to growth medium supplemented with insulin and T3, which was then changed every second day. After four to five more days in this medium, cells exhibited a fully differentiated phenotype with massive lipid accumulation.

Example 1

To examine the function of ACATs in obesity, the expression patterns of ACAT1 and ACAT2 genes, and their gene products during adipogenesis of murine 3T3-L1 preadipocytes in vitro were examined. ACAT1 mRNA level was markedly increased in adipocytes from 2 days after initiation of adipogenesis (i.e., D2) as judged by real-time PCR assay (FIG. 1). However, ACAT2 mRNA level was similar between preadipocytes (D0) and mature adipocytes (D6) while a temporal reduction of ACAT2 level was observed at D2 (FIG. 1). In addition, white adipose tissue (WAT) isolated from high fat diet-induced obese mice displayed elevated mRNA level of ACAT1 and reduced mRNA level of ACAT2 when compared with those in lean mice as judged by real-time PCR assay. Leptin level was measured in WAT from lean and obese mice to ensure the development of obesity (FIG. 2). In addition, brown adipose tissue (BAT) from obese mice exhibited elevated levels of both ACAT1 and ACAT2. Uncoupling protein-1 (UCP-1) level was measured in BAT from lean and obese mice as a BAT-specific marker protein (FIG. 2). However, liver from lean and obese mice exhibited similar levels of ACAT1 and ACAT2 (FIG. 2).

The anti-adipogenic activity was assessed in the 3T3-L1 cell line using the methods explained by Pandeya et al22 (link) 3T3-L1 preadipocytes were cultured and subcultured in 10% NCS supplemented with DMEM growth medium with 1% antibiotics (penicillin–streptomycin). Cells were maintained under a humidified atmosphere of 5% CO2 at 37°C. Then, the obtained cells were seeded in a 96-well plate at a cell density of 7×103 cells per well and left overnight. The next day, the cells were treated with different concentrations of plant extracts in 10% FBS-supplemented DMEM. After 48 hours, the MTT assay was performed to calculate cell viability at different concentrations. Thus, a safe dose was used to evaluate the anti-adipogenic activity.
The Oil Red O (ORO) staining assay was used to quantify the amount of lipid deposited in differentiated 3T3-L1 cells. 3T3-L1 preadipocytes were seeded into the 24-well plate at a cell density of 5×103 cells per well in 10% FBS-supplemented DMEM culture medium. The cultured plates were kept in an incubator until cells reached full confluency, and the cell medium was changed every 2 days. After that, cells were co-treated with non-toxic concentrations of extracts (obtained by the MTT assay) in cell differentiation media for 2 days. The cell differentiation media contained dexamethasone (1 µM), insulin (5 µg/mL), and 3-isobutyl-2-methylxanthine (IBMX 0.5 mM) in 10% FBS-supplemented DMEM. Differentiation media with the tested concentrations of extracts were replaced after 2 days by adipocyte maintenance medium (10% FBS-supplemented DMEM with 5 µg/mL of insulin; without extracts). After 2 days, the adipocyte maintenance medium was replaced by 10% FBS-supplemented DMEM. On the eighth day of the experiment, cells were washed with phosphate-buffered saline and fixed in 10% formalin. Fixed cells were stained with ORO and viewed under an EVOS XL (Life Technologies, USA) microscope. The deposited stain was dissolved in isopropanol and quantified using a microplate reader at 520 nm.
The final results were expressed as percentage deposition of lipid in differentiated cells compared to control, as follows:

More about "3T3-L1 Cells"

3T3-L1 cells are a widely-used mouse-derived embryonic fibroblast cell line that can differentiate into adipocytes (fat cells) under the right culture conditions.
These versatile cells have become a crucial model system for studying the cellular and molecular mechanisms underlying adipogenesis (fat cell formation), lipid metabolism, and insulin signaling pathways - key processes involved in conditions like obesity, diabetes, and other metabolic disorders.
The 3T3-L1 cell line is known for its rapid proliferation and robust differentiation capabilities when exposed to appropriate hormonal stimuli, making it an invaluable tool for researchers investigating adipose tissue development and function.
These preadipocytes can be induced to undergo adipocyte differentiation through the addition of a cocktail of adipogenic inducers, such as dexamethasone, insulin, and 3-isobutyl-1-methylxanthine (IBMX), in a defined culture medium like DMEM supplemented with fetal bovine serum (FBS) and penicillin/streptomycin.
During the differentiation process, the 3T3-L1 cells accumulate lipids, which can be visualized using lipid-specific stains like Oil Red O.
Researchers often utilize molecular biology techniques, such as TRIzol reagent for RNA extraction, to study the expression of adipogenic marker genes and signaling pathways that drive the transformation of fibroblasts into mature, functional adipocytes.
The 3T3-L1 cell model has been instrumental in advancing our understanding of adipose tissue biology and the underlying mechanisms of metabolic disorders, providing valuable insights for the development of potential therapeutic interventions.
